the match of Kendo

As you imagine, players usually move actively and try to attack many times. But, it seems this is not always applicable to the experts. 

The notable match took place on November 23. In this match, each player hardly move before the match ends. Even they are the masters.

From I, have few experience of Kendo, this match seems funny. But some people highly praised this match. I assume it is difficult to understand Kendo even for Japanese.
